Okay, so my friend and me made an experiment yesterday. We wanted to brew a >20%, 300+ IBU IIPA.
Yeah yeah... I know :)
Now to the question. We used 10.5kg of grain for 26.25 liters of water for the mash. From the recipe calculator, we should have gotten around 1.208 OG. We "only" managed to get it to 1.120.
I wanted to ask if anyone had an idea of that poor efficiency. Mash went wonderfully at a temperature of 66°C.
- Is there some point where converting to sugars in mash gets a lot harder?
- Is the hydrometer capable of reading very high gravity readings?
- Is there anything that you can think of that could create this result?
This is for a 3 gallons batch (11.5 liters).
